Looks interesting. I guess I was wondering if anyone had actually removed the RBC's and punched holes in the running boards and applied an aftermarket stiffener, i.e. better boards, so they would effectively reduce some tunnel drag in the snow. Seems like all of the mountain tunnels today have large openings on the running boards for snow evacuation and reduced snow buildup (weight). If I did this would I have a 'plumbing' and cooling issue, even if I did install a larger tunnel mounted cooler? Add scratchers to help?
